Abstract

Disclosed are traceable polymeric additives that comprise a tagging material and methods of using the traceable polymeric additives in subterranean applications, such as cementing. An embodiment discloses a method of well treatment comprising introducing a fluid comprising a traceable polymeric additive into a wellbore, wherein the traceable polymeric additive comprises a polymer and a tagging material.

Claims

1. A method of well treatment comprising:

introducing a fluid comprising a traceable polymeric additive into a wellbore, wherein the traceable polymeric additive is particulate in form and comprises a swellable elastomer and a tagging material;

wherein the tagging material comprises a thermal neutron absorbing material;

wherein a weight ratio of the elastomer to the tagging material is about 99;

1 to about 0.1;

1; and

wherein the swellable elastomer comprises at least one polymer selected from the group consisting of a water swellable polymer, oil swellable polymer, dual oil and water swellable polymer, and combinations thereof.

2. The method of claim 1 wherein at least a portion of the tagging material is dispersed in the at least one polymer.

3. The method of claim 1 wherein the tagging material is present in a coating on the at least one polymer.

4. The method of claim 1 wherein the tagging material thermal neutron absorbing material is selected from the group consisting of cadmium, boron, gadolinium, iridium, boron carbide, boron nitride, boric acid, boron concentrated glass, zinc borate, borax, gadolinium oxide, gadolinium acetate, gadolinium concentrated glass, and any combination thereof.

5. The method of claim 1 wherein the swellable elastomer comprises at least one elastomer selected from the group consisting of natural rubber, acrylate butadiene rubber, polyacrylate rubber, isoprene rubber, choloroprene rubber, butyl rubber, brominated butyl rubber, chlorinated butyl rubber, chlorinated polyethylene rubber, neoprene rubber, styrene butadiene copolymer rubber, sulphonated polyethylene, ethylene acrylate rubber, epichlorohydrin ethylene oxide copolymer rubber, ethylene-propylene rubber, ethylene-propylene-diene terpolymer rubber, ethylene vinyl acetate copolymer, a fluorosilicone rubber, a silicone rubber, poly 2,2,1-bicyclo heptene (polynorborneane), alkylstyrene, a block copolymer of styrene-butadiene rubber, nitrile rubber, hydrogenated nitrile rubber, a fluoro rubber, a perfluoro rubber, a tetrafluorethylene/propylene, an isobutylene maleic anhydride, and any combination thereof.

6. The method of claim 1 wherein the fluid further comprises a hydraulic cement and water, and wherein the method further comprises allowing the fluid to set in the wellbore.

7. The method of claim 6 wherein the fluid is used in primary cementing.

8. The method of claim 6 wherein the traceable polymeric additive is included in the fluid in an amount of about 0.1% to about 100% by weight of the hydraulic cement.

9. The method of claim 1 wherein the introducing comprises pumping the fluid through a casing and into a wellbore annulus.

10. The method of claim 1 wherein the fluid is introduced into the wellbore to displace a drilling fluid from the wellbore, the fluid separating the drilling fluid from a cement composition, and wherein at least a portion of the traceable polymeric additive reduces in volume to affect annular pressure in response to a compressive force in the wellbore.

11. The method of claim 1 further comprising running a neutron log on one or more intervals of the wellbore after the introduction of the fluid;

and detecting location of the traceable polymeric additive based on the neutron log.

12. A method of well cementing comprising:

providing a cement composition comprising cement, water, and a traceable polymeric additive wherein the traceable polymeric additive is particulate in form and comprises a swellable elastomer and a tagging material, wherein the tagging material comprises a thermal neutron absorbing material;

wherein a weight ratio of the elastomer to the tagging material is about 99;

1 to about 0.1;

1; and

wherein the swellable elastomer comprises a polymer selected from the group consisting of a water swellable polymer, oil swellable polymer, dual oil and water swellable polymer, and combinations thereof;

introducing the cement composition into a wellbore; and

allowing the cement composition to set.

13. The method of claim 12 wherein the traceable polymeric additive is included in the cement composition in an amount of about 0.1% to about 100% by weight of the cement.

14. The method of claim 12 wherein at least a portion of the tagging material is dispersed in the polymer.

15. The method of claim 12 wherein the tagging material is present in a coating on the polymer.

16. The method of claim 12 wherein the thermal neutron absorbing material is selected from the group consisting of cadmium, boron, gadolinium, iridium, boron carbide, boron nitride, boric acid, boron concentrated glass, zinc borate, borax, gadolinium oxide, gadolinium acetate, gadolinium concentrated glass, and any combination thereof.

17. The method of claim 12 running a neutron log on one or more intervals of the wellbore after the introduction of the cement composition, and detecting a location of the traceable polymeric additive based on the neutron log.

18. The method of claim 12 further comprising tracking location of the traceable polymeric additive in the wellbore by detection of the tagging material.
